There are many causes of short stature, but the following four are more common clinically: 1. Genetic and family factors: If there are members in the family with short stature, then the next generation is more likely to suffer from dwarfism. However, genetic factors can also be influenced by environmental factors of growth later in life.
2. Low birth weight and length: If the child’s weight at birth is lower than the normal birth weight (usually 2.5 kg), whether it is a premature or full-term child, most of these children are shorter than those with normal birth weight and height at all ages and in their final adulthood.
3, nutrition and disease: the mother’s nutrition during pregnancy is crucial to the growth of the fetus, if the mother has severe malnutrition during pregnancy, or is suffering from chronic heart, lung, liver and kidney disease, may cause fetal growth disorders, making the child in the fetal period and after birth height are lower than normal.
4. Some endocrine diseases: for example, growth hormone, which is closely related to height growth after birth, may cause short stature of children if there is a lack of growth hormone; another example is thyroxine, which can regulate the body’s metabolism.
